To oil something is to put oil on something, or to grease something.I wonder if oil could be used like this, I know it's a verb sometimes.
I didn’t say it work exactly the same as an oil, Andy. I said it works ‘like’ an oil; you can fry with it the same way you can oil. Whether the statement is correct or not isn’t the point, anyway; I was interpreting what I thought Silver’s student may have been trying to say.But it doesn't. Not until the water content has evaporated.
